Weidmüller BLF 5.08HC/10/90LR SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/10/90LR SN BK BX is a female PCB connector built for industrial electronics, control interfaces, and board-level field wiring where dependable pluggable connectivity is a priority. As part of the OMNIMATE Signal BL/SL 5.08 family, it combines a 5.08 mm pitch, 10 poles, and a 90° conductor outlet with PUSH IN spring connection technology. That makes it highly relevant for engineers looking for a connector that supports fast wiring, compact installation, and easier servicing over the full product lifecycle.
What the Weidmüller BLF 5.08HC/10/90LR SN BK BX Is
This product is a female plug-in PCB connector intended for field wiring on printed circuit boards. Its 10-pole format allows several circuits to be grouped into one organized pluggable connection point. That is useful in industrial control systems, machine electronics, and modular interface boards where service access and connection clarity both matter.
Technical Specifications
The Weidmüller BLF 5.08HC/10/90LR SN BK BX is rated at 400 V and 24 A according to IEC values, with a conductor range of 0.2 to 2.5 mm². Under UL data, it is rated at 300 V and 18.5 A with conductor sizes from AWG 26 to AWG 12. The maximum clamping range is 3.31 mm². These values position it well for industrial board-level signal and power distribution tasks where reliable performance is essential.
Design Advantages
The connector uses PUSH IN with actuator technology, which supports faster installation and more predictable conductor handling. In production environments, this can improve wiring efficiency. In service situations, it supports quicker maintenance and easier reconnection. The 90° conductor outlet also helps guide wires in a controlled direction, which is useful in compact or tightly arranged assemblies.
Why This 10-Pole Connector Matters
A 10-pole pluggable terminal block connector is often chosen when multiple signals or power lines need to be integrated on one board in a clean and maintainable way. The Weidmüller BLF 5.08HC/10/90LR SN BK BX supports that need without forcing a move to more complex or oversized connection hardware. It offers a practical balance between connection density and accessibility.
Material and Environmental Profile
The connector is designed for industrial-grade performance and aligns with the broader BLF 5.08HC family known for robust materials, compact design, and compliance-oriented construction. It is suitable for applications where long-term stability and standardized component sourcing are important.
Typical Applications
Common use cases include automation modules, controller boards, compact machine interfaces, industrial electronics, and serviceable terminal interfaces in equipment that benefits from pluggable PCB connections.
